Automounter
Radomir Zoltowski
Could you lads give me a hand with setting up FreeBSD 4.0 NIS/NFS client
with Sun Solaris NIS/NFS 2.6 server?
I have faced a problem with automounter. I CAN mount any FS from any Sun
machine, but no FS is mounted automatically. Also I can't log in to
FreeBSD with NIS user and password. However I CAN perform su!.
I have already followed all the steps from Handbook, but it looks like I
need some more sophisticated documents to read...
Thanks in advance,
R.

I think your problem is that your Solaris system uses a different
automounter from FreeBSD. Solaris uses autofs, like Linux, while
FreeBSD uses the AutoMount Daemon (AMD).
Autofs automount maps are not compatible with AMD, and vice versa.
Theoretically, you should be able to compile and run AMD on Solaris.
If you can't, or won't, do that, you are out of luck.
This is the reason why I only use BSDs for servers, and not
workstations.
Sincerely,
Lars Josephsen

This is correct.

You might as well write the propper maps and let them serve by
NIS. Like amd.master (and friends) in addition to auto.master (and
friends).
This might not work as I figure:
Example from my rc.conf (a Sun is NIS-Master serving autofs and amd
maps...).
# Automounter
amd_enable="YES"
amd_flags="-c 1800 -k i386 -l syslog"
amd_map_program="ypcat -k amd.master"
Since the amd_map_program could be anything - you *might* try to
get an on the fly conversion with some script and ypcat -k auto.master...

Uhhh? In case you did not notice: Sun builds servers (and work-
stations...)
Try to replace a typical E450 server with PC Hardware. Good
luck... (and this is really a small server...)

Hello.
If you want to `su' from a NIS user, you have to make him/her a member
of the local group `wheel'.
For the NFS automounter, I have modified my NIS Makefile on the
Solaris (2.7) master server so that it generates AMD NIS maps using
AUTOFS maps through this little perl script I found some months ago,
called `/sbin/sun2amd'
[BEGIN]
#!/usr/local/bin/perl
printf "# generated by sun2amd\n";
printf "/defaults\ttype:=nfs;fs:=\${autodir}/\${path}\n";
# loop through map
while (<>) {
if (m,^([\w\*]\S*)(\s+\-\w\S*\s+|\s+)(\w[^:]*):(\/\S*)\s*(.*),) {
($dir, $options, $machine, $path, $rest) = ($1, $2, $3, $4, $5);
print "#$rest\n" if ($rest =~ m/\w/);
if ($options =~ m/-/) {
$options =~ s/ //g;
print "## options: $options\n";
$has_options++;
}
$path =~ s/\&/\$\{key\}/g;
print "$dir\trhost:=$machine;rfs:=$path\n";
}
}
[END]
Here is a sample from the Makefile :
...
all: passwd group hosts ethers networks rpc services protocols \
netgroup bootparams publickey netid netmasks c2secure \
timezone auto.master auto.home auto.import auto.direct \
amd.home amd.import \
...
$(DIR)/amd_home : $(DIR)/auto_home
/sbin/sun2amd < $(DIR)/auto_home > $(DIR)/amd_home
amd.home.time : $(DIR)/amd_home
@sed -e "/^#/d" -e s/#.*$$// $(DIR)/amd_home \
| $(MAKEDBM) - $(YPDBDIR)/$(DOM)/amd.home; \
if [ ! $(NOPUSH) ]; then $(YPPUSH) amd.home; fi ; \
touch amd.home.time ; \
echo "updated amd.home"
amd.home: amd.home.time
...
On the FreeBSD client, AMD is started with the values in rc.conf :
amd_enable="YES"
amd_flags="-a /a -l syslog /net /etc/amd.map /home amd.home"
Hope this helps.
Regards.
Nicolas.

No, you don't need to run amd on Solaris. What you need is to maintain a
separate set of amd maps on your NIS server (or update config files manually
on the clients). I haven't done this for years myself, but I've attached a
script I used for doing automount->amd conversion.
This was on a SunOS NIS server, it may need some tweaking for
Solaris/autofs.
With small modifications to the NIS Makefile you can automate this to
convert and push corresponding amd maps whenever autofs-files are
updated.

Thanks, I have a lot to try...
